Chapter 19, Problem 106FP

Consider two cells involving two metals X and Y

   $\begin{array}{c}\text{X}\left(\text{s}\right)\left|{\text{X}}^{\text{+}}\left(\text{aq}\right)\right||{\text{H}}^{\text{+}}\left(\text{aq}\right),{\text{H}}_{\text{2}}\left(g,1\text{bar}\right)|\text{Pt}\left(\text{s}\right)\\ \text{X}\left(\text{s}\right){\text{X}}^{\text{+}}\left(\text{aq}\right)\left|\right|{\text{Y}}^{2+}\left(\text{aq}\right)|\text{Y}\left(\text{s}\right)\end{array}$

In the first cell electrons flow from the metal X to the standard hydrogen electrode. In the second cell electrons flow from metal $X$ to metal Y. Is $E_{xx}^0>E_{yzy}$ ? Explain.
